"plumber" even bigger scam artist than I thought? (whole house water pressure)
Last summer I discovered there was a pinhole in the incoming water line between the city shut-off at the curb and my house---on my side, naturally. Told repair would require backhoe, about 4-5k, and replacing entire (about 15 ft or longer) line, tunneling under my 1937 brick porch and to the foundation/basement, uprooting small trees. All this for a pinhole out in the open lawn. I asked if it is possible to weld a new segment of pipe, because frankly I didn't have 5k and knew that my porch would crack, too. I was told yes, maybe, I'll ask my master plumber. Long story short, this was done without my final approval, Turns out this contractor was dishonest, contract was on a letterhead from defunct business, etc... and ever since the repair, the entire house has nightmarishly low water pressure. I've checked all the faucet filters, etc. I'm afraid when he welded the (already tiny lumen) pipe, he might have let the welding material ooze and harden inside the pipe, shutting off half the flow. Is there any hope it's a whole-house filter or valve that's clogged in my case? It takes 8 minutes to fill the kitchen sink, open full blast. There's not even enough pressure to run the DW or use a sink sprayer! I had hoped to add a BR upstairs but can barely flush the one I've got, now. Grateful for any advice I can get.--Anne
